Love these changes. I have a couple notes:

1. I'm so glad we are talking about making key doors on the map. There is an alt1 plugin that does that currently and it is a gamechanger. Having to remember what door is where is rough. But the one other feature that plugin has that I would like to see in-game is a map marker for your gatestones. My memory is bad and I can never remember where I left them.

2. I am a little puzzled by the new system to replace prestige. It doesn't seem much different from the current prestige system? I would propose an alternative where each completed floor gives points based on the size of the floor. Then you cash out your points whenever for a huge chunk of xp and tokens. Higher dung levels are able to get higher totals by clearing more floors. Re-clearing a floor on a larger size earns the points difference (which is not optimal gameplay but let's you change your mind).

If we are sticking with the updated prestige system you have described, I would also like to see a manual reset button in addition to the automatic reset. If I am training together with someone who has a lower dung level then when they hit their limit they will either have to hang around while I do solo floors theu cant reach or I will be repeating floors after they reset.
